| 103 | help |
| 104 | kexec is a system call that implements the ability to shutdown your |
| 105 | current kernel, and to start another kernel. It is like a reboot |
| 106 | but it is independent of the system firmware. And like a reboot |
| 107 | you can start any kernel with it, not just Linux. |
| 108 | |
| 109 | The name comes from the similarity to the exec system call. |
| 110 | |
| 111 | It is an ongoing process to be certain the hardware in a machine |
| 112 | is properly shutdown, so do not be surprised if this code does not |
| 113 | initially work for you. As of this writing the exact hardware |
| 114 | interface is strongly in flux, so no good recommendation can be |
